To all whom it may concern:

Be it known that I, WILLIAM W. JACQUES, of the city of Baltimore and State of Maryland, have invented a new and useful Improvement in Underground -Telegraph Wires, of which the following is a specification.

My invention has for its object to surround or inclose an electrical conducting substance, such as copper wire, with flexible insulating material having certain desirable characteristics, to wit: convenient' to manipulate, not

easily destructible, suitable tobe laid directly in the earth, or in pipes, drains, &c., not afl'ected by the ordinaryelements or constituents of the soil, be repellant to water, not affected by heat or cold within the limits to .whichit would ordinarily be subjected, that while flexible it will not crack when bent short, and, further, be of such character that the several enumerated properties will not be lost or changed by time. i

The invention consists in surrounding or enveloping a wire with some fibrous material, suchas cotton, saturated with an insulating solution, in a warm state, of bees-wax and Venice turpentine.

In carrying out my invention I prefer to combine beeswax, five parts, with Venice turpentine, two parts, which are properly incorporated by the aid of heat. The exact proportions named are, however, not essential, the only object being to attain such a consistency that it will neither harden with cold nor become liquid with heat within the limits of temperature to which it would ordinarily be subjected in the ground.

1n the drawings hereto annexed, Figure l is a view of the underground wire, lead-incased, partly in section. Fig. 2 is a view of the insulated wire without the leadcase. Fig. 3 illustrates the completed article coiled. Fig. 4 is a cross-section of same.

desire to secure by which serves to protect the enveloping insulating material from the attacks of insects, or

from puncture, cutting, or abrasion caused by contact with hard substances when the article is handled.

Thus constructed the wire is flexible, and adapted to be coiled orpnt on reels and other wise hand-led in manner similar to ordinary wire.

I am aware that telegraph-wireshave heretofore been wrapped or surrounded with cords or bands of fibrous material saturated or coated.

with insulating compounds, and also that such wires have been inclosed in pipes or tubes. I .do not, therefore, claim such, broadly; but,

Having described my invention, I claim and United States Letters Patent- 1. A compound for insulating telegraphwires, consisting of bees-wax and Venice turpentine, combined substantially as set forth.

'2. The combination, substantially as set insulating compound consisting of bees-wax and Venice turpentine, combined substan tially as described, surrounding the wire.
